3 0

Answer:

x= 4/5 or x = -2

Step-by-step explanation:

Step 1: Subtract -6x from both sides.

5x^2 -8 - -6x = -6x -6x

5x^2 + 6x - 8 = 0

Step 2: Factor left side of equation.

(5x - 4) (x + 2) = 0

Step 3: Set factors equal to 0.

5x - 4 = 0 or x + 2 = 0

Hense the Answer is x= 4/5 or x = -2

qwelly [4]

Answer:

$S.E=1183.2$

Step-by-step explanation:

From the question we are told that:

Population mean $\mu=60000$

Population standard deviation $\sigma= 14,000 miles.$

Sample size $n=140$

Generally the equation for Standard error is mathematically given by

$S.E=\frac{ \sigma}{ \sqrt n}$

$S.E= \frac{14000}{\sqrt 140}$

$S.E=1183$

Find the two straight lines represented by x² + 5xy - 6y² = 0

Andreyy89

By factorizing, we have

$x^2 + 5xy - 6y^2 = (x - y) (x + 6y) = 0$

so that

$x - y = 0 \implies \boxed{y = x}$

or

$x + 6y = 0 \implies \boxed{y = -\dfrac x6}$
